"2024 sees 5% drop in U.S. engagement ring spending, with lab-grown diamonds now over 50% of center stones. Average carat size rises to 1.7 as couples prioritize value. Explore trends in designs, metals, and the natural vs lab-grown diamond divide."

一． What materials are synthetic diamonds made of?Synthetic diamonds are polycrystalline diamonds made from the aggregation of diamond crystals with a diameter of 10 to 30 nanometers. The manufacturing process is similar to the process by which diamonds form naturally.There are two main types of mate
